Bondtech Heat Break Kit for Prusa Mini
To solve Heat creep with your Prusa Mini
This Stainless Steel Bondtech Heat Break Kit for Prusa Mini addresses and solves the heat-creep issues revealed during the extensive testing we performed on the Prusa Mini.
The adjusted length of the PTFE tube also prevents clogs to form between tube and heat-break.
Included in this kit:
- 1x 32×5.48 mm stainless steel heat-break
- 1x 35.3 mm 2/4 chamfered PTFE tube
- 1x Silver based thermal paste bag 
We recommend to use the included silver based thermal grease to properly fit the Bondtech heat-break in the Mini’s heat-sink.
Notes on twisting the heat break
To address the heat creep issue the design features a narrower section with thinner walls. When removing the heater block or changing nozzles, caution is required.
Before removing the heater block from the heat break (or vice versa), heat-up the nozzle, hold the heater block and release some tightening pressure from the nozzle. Let the whole group cool down. After, you can simply unscrew the heat break from the heater block.
To remove or replace a nozzle, never forget to secure the heater block before twisting the nozzle.
